Kevin McConway, emeritus professor of applied statistics at the Open University, who was not involved with the research, praised the modelling but warned that much would depend on policy and behaviour. It also depends on the extent to which the relationship between fertility on the one hand, and access to education and modern contraception on the other, works in a similar way in the future as it did in the past.
